De novo transcriptome assembly of the grapevine phylloxera allows identification of genes differentially expressed between leaf- and root-feeding forms.

ABSTRACT:

Background

Grapevine phylloxera, an insect related to true aphids, is a major historic pest of viticulture only controlled through the selection of resistant rootstocks or through quarantine regulations where grapevine is cultivated own-rooted. Transcriptomic data could help understand the bases of its original life-traits, including a striking case of polyphenism, with forms feeding on roots and forms feeding in leaf-galls. Comparisons with true aphids (for which complete genomes have been sequenced) should also allow to link differences in life-traits of the two groups with changes in gene repertoires or shifts in patterns of expression.

Results

We sequenced transcriptomes of the grapevine phylloxera (Illumina technology), choosing three life-stages (adults on roots or on
